With all the help I received our Harmony Elite and Hub are back in control. It appears that the OPPO players need a power "ON" and a power "OFF" using the unit's power button when there has been a power loss. I had disconnected them from power using their power cords.
Both my OPPO players (BDP-93 & UDP-203) have lost IR contact with our Harmony Elite Hub after some house cleaning and reorganization. Both OPPOs respond to their respective controllers.
I'm using a Harmony Elite and it's hub to control all my home entertainment equipment. I have a small room on the other side of a living room wall where the TV is hung. All the other gear is in an open rack that stands beside my computer desk. Until I got my foot tangled up in it's wire I had a mini blaster going from the Hub through the wall to the TV. A new mini blaster will be here today.
The rack holds the cable box, a Roku 3, Roku Ultra, a four to one HDMI switch on the first shelf.
At the moment the next shelf just has the Hub and a power strip for all the transformers.
The third shelf has an OPPO 93 and an OPPO 203.
The fourth shelf has the AVR.
The fifth shelf doesn't have anything that's Harmony controlled. There is nothing on the very top shelf either.
Before I broke the wire to the TV mini blaster, the Hub got IR signals to all components in the rack without needing any special care about the Hub location. That's been true since I added the OPPO 203 to the rack.
Now the Hub is getting IR signals to every component but the two OPPO players on shelf three. I've tried moving the Hub to the OPPO shelf without a response from the players, and then I switched to a mini blaster on the OPPO shelf. The mini blaster is located about four inches from the IR receivers in the OPPO players. There is still no response to commands from the Hub.
Is there anything about disconnecting the OPPO players from power that could put them in a state where they respond to their own controllers but not to the Harmony?
I can't think of anything else to test.
